14– Imam Ali (AS) said, ‘It is enough for a person … endowed with intellect to be fair
[to others] in spite of himself … and
[for a person] endowed with fairness to accept the truth when it becomes clear to him.’
[Kashf al-Ghamma, v. 3, p. 137-138]

15– Imam Ali (AS), in his letter to Malik al-Ashtar said, ‘…be fair for Allah and be fair to people in spite of yourself, and in spite of your close members of your family, and in spite of those towards whom you have inclinations from among your followers, for if you do not do so you will be oppressing.’
[Nahj al-Balagha, Letter 53]

مَن لا يَنتَصِفُ / Those who are not fair

17– Imam Ali (AS) said, ‘There are three types of people who cannot expect fairness from three other types of people: an intelligent man from a fool, a righteous man from a corrupt man, and a kind man from a vile man.’
